Within each structural category the ' ' Si chemical shift is correlated with the Si-0-Si bond angles and the interatomic distances. We conclude that, in agreement with the est
## Abstract In four series of strictly related organocobalt complexes, derived from cobaloximes by replacement of the Oβ¦Hβ¦O with Oβ¦βBF~2~β¦O and/or (CH~2~)~3~ groups, the trends of ^59^CoβNMR shielding and electrochemical data are discussed. A largely parallel behaviour of the plots of E~1/2~(I) val
Three new derivatives of vitamin B, ?. 0"-succinyl-, 05'-s~~cinyl-, and 02'. 0"-disuccinyl-vitamin B, 1. whose a-ribose moieties of the nucleotide ligand are succinylated, were prepared by reaction of the vitamin with succinic anhydride. The first succinylstion took place rapidly and almost predomin
